# Note:
* This script is a basic example and may need modifications depending on your specific environment.
* Make sure you have the necessary permissions to perform these actions in vCenter Server.
* You can customize the script by adding additional parameters for VM configuration, such as network settings, NICs, etc.

I hope this helps! Let me know if you have any other questions.
